1. A piezo-electric power source comprising:
a stack of piezo-electric elements that are electrically connected in serial, wherein the piezo-electric elements of the stack are responsive to mechanical pressure to produce electrical power; and
a control circuit electrically connected to the stack of piezo-electric elements for converting the electrical power from one temporal duration to another temporal duration and the control circuit is adapted to convert a press duration that is a temporal duration that mechanical pressure is applied to the stack of piezo-electric elements to an output duration during which energy is output,
wherein the control circuit controls the output duration to be temporally delayed from the press duration by at least one msec.
